I am Dutch. We have a steel, 12 meter trawler yacht which we regularly take out on the North Sea and on the Baltic. Two years ago we had a Magnus Master stabilizer installed. The result has exceeded our expectations and we have not had any problems with the system.
Very instructive video on a principle I am very familiar with but have never seen applied for this purpose. I bet that absolutely gorgeous 4-legged "first mate" is impressed as well.
It is called a pleasure craft, not a commercial vessel. It for all types - including landlubbers - not just “old salts” Comfort and passenger’s without sea sickness is important.
28:30 thats a very impressive turn rate with virtually no movement fro level. Wow colour me impressed.. Ive seen these were fitted on mv astra to good effect but im surprised just one can work so well on a smaller boat
Nice job on the video. Very cool installation. Any worries that the Magnus Master sticking out the back is exposed being hit on a dock if backed in? No med mooring in the USA for course. 🙂
Not at all I keep an eye on it around pylons when docking. Its when it is extended I watch for crab traps. If I was to run over one, I go into neutral and pass over the trap with no prop running and the system starts to park . But no clearance problem except for that.
Lots of questions. How much rudder angle is required while underway? What is your difference in speed through the water? Is there a release function/shear pin for when this strikes a tide-walker (log) or catches on a crab or lobster pot? Does it have a tear away weak link like the forward facing twin prop outdrives, or are you prepared with giant bilge pumps? These are serious questions.
The angle difference is slight but autopilot corrects. In manual steering you can't tell any difference except for when you deploy it, the MMS will present a noticeable pull to port for the 13 seconds it takes to deploy. Then it smooths out and no more pull. Speed in the water is about 1/10 of a knot. There is a set of shear pins under a bolt cover I can reach easily and replace if I was to hit a channel marker for an example. About 30 minuets and $1.00 in parts. Crab and lobster pots worry me but so far, my procedure when I don't see a pot in time, is to put the throttle in neutral to stop my prop but at the same time the MMS goes into park automatically and if the pot was caught on the arm, it would slip off as it parks.
good to see a "real life" video of this system. Well done. Question -- is it always a manual deploy? As in, you have to push the button to deploy it? Or does it auto deploy as soon as you go in gear and/or reach a certain speed?
Always manual but it will auto park when in neutral, which is good when you run over a crab trap. You automatically throw the throttle in neutral to stop the prop and at the same time the stabilizer parks.
I’m just curious why you didn’t have it when it was in its parked position. It was facing forward instead of backwards.? I would think that would be better cause then you wouldn’t have anything sticking out the back of your boat to get damaged just a thought!!
That's a very cool idea. I don't see why that would not work. But we decided this way and I look down at it when looking over the stern and like seeing it to monitor the algae growth. My stern thruster has a guard around it which helps guard the rear area. But your idea is outside of the box thinking. Thanks.
I'm curious if marine fouling is an issue with this system, any moreso than with any running gear...vibration, reduced effectiveness, issues with the extension and retraction, etc.
I bet these things sticking out of your hull must cause quite some drag; they don’t look hydrodynamic at all. I would rather install electromagnetic stabilizer like “Waveless Stab 20” from CMC Marine.
1/10 of a knot which is a gallon of fuel for every 13 miles. We travel about 50-60 miles per cruise day. This runs around $20.00 per day extra which is about the cost of an Uber. We find it very much worth the cost. But we are still measuring and will post in our videos more data.
Is it true these don’t have any effect at anchor? This is one of my concerns - would like to be able hang out at anchor to dive etc and have boat be still as possible. Any input appreciated.
The DMS does not work at anchor...unless there is a 5 knot current. We choose it because we are more in need when we cruise at sea. We can pick calm anchorages. But I wish it did because we do get hit with wakes and some weather when we are moored. But that is the only con on the system. It needs water passing over it. So it will work when being towed.
Flopper Stoppers are great for anchoring or mooring if that is your situation. We are full time cruisers and require stabilization on the move. A rolling stone gathers no moss... or in this case, no algae. Besides, we pick our anchorages in calm protected waters to not need a Flopper Stopper.
Having served on two sided trawlers, in the north sea Iceland - Bear Island - Norwegian sea - faro's and served on Lightships - what's a bit of role? nothing a hardened sailor would just take it his stride. it was flat calm during the filming what are you going to do if it gets choppy let al-own rough. Force 12 in a 40ft pilot boat was no fun after 12 hours.
As our videos show, we are no stranger to rough seas. The additional stabilizer does not turn our boat into a zero pitch and roll boat. My beer will still spill in rough seas. But it does allow us to go out in larger seas. Increases our weather windows. 5-6 foot head or following seas will still send waves over the deck. Since this is a pleasure craft, my job is to make it as pleasurable as possible for my crew. We choose our weather the best we can but the seas have some level of unpredictability. We have been caught out in waves and storms, battling the elements. 50-60 mph winds and 5 foot waves has all hands working and no free hand to film. I personally love the challenge and excitement but my wife and dog... not so much. It's during these situations we have said we were glad we were in a Nordhavn. Now we can say, : a Nordhavn with a stabilizer".
Because it might be what they want. People are allowed to have different goals and ideas. Even if you perceive them to be "wrong" according to your high standard

Hast du einen Arm oder zwei Arme von den Stabilisatoren? Also auch nur auf einer Seite, oder auf beiden Seiten (Steuerbord und Backbord)?
Nice video. I met Patrick at the Annapolis boat show where he took me out for a short sea trial. Pretty amazing system.
I always wondered how well the DMS MagnusMaster system worked. Very impressive.
Guys,
This is so great. I’m very glad it’s worked for you!
Very instructive video on a principle I am very familiar with but have never seen applied for this purpose. I bet that absolutely gorgeous 4-legged "first mate" is impressed as well.

Very cool new system. It's going to replace fin stabilizers for sure. We will install these on our Helmsmen when we order.
Oh my goodness, think about the consequences first.
ROCK-N-ROLL!! arrrrr no, not anymore! Be happy, be safe

Well, I’m impressed.
How much drag in induced when its deployed?
1/10 to 2/10 knots. I figure about a gallon of gas per 8 hr. cruise.
I wonder about the long term reliability of the spinning rotor and bearings etc
DMS prides themselves on low maintenance. Very little moving parts compared to a gyro system.
I’m just curious why you didn’t have it when it was in its parked position. It was facing forward instead of backwards.? I would think that would be better cause then you wouldn’t have anything sticking out the back of your boat to get damaged just a thought!!

Are we just going to let the "aft torpedo tube" slide? Seriously I laughed out so hard I had to put my coffee down.
So what would be the cost of the system, installation would be separate?

Awesome demonstration at 27:46! How much does this system increase fuel consumption?
1/10 of a knot which is a gallon of fuel for every 13 miles. We travel about 50-60 miles per cruise day. This runs around $20.00 per day extra which is about the cost of an Uber. We find it very much worth the cost. But we are still measuring and will post in our videos more data.
@@mvmoondance1283 Not nearly as much as I would have thought. Thank you for the reply!

Looks Like I will stick too my Flopper Stoppers ! Why you ask ? Well the work when the boat is not underway !
Flopper Stoppers are great for anchoring or mooring if that is your situation. We are full time cruisers and require stabilization on the move. A rolling stone gathers no moss... or in this case, no algae. Besides, we pick our anchorages in calm protected waters to not need a Flopper Stopper.
@@mvmoondance1283 I guess no one told you but Flopper Stoppers do a great job while cruising and for a lot better price than those Dutch thingys !
@@moejaime2654 Paravanes are for moving, flopper stoppers are for at rest. What am I missing?
Flopper Stoppers do both !
Looks like it creates a lot of drag.
nope hardly any fins are worse
If it ain't Dutch, it ain't much !!
Are they zero speed?
No. You need to be moving over 4-5 knots. We travel at 9 knots.
Creates a lot of drag.
It adds 1/10 of a knot drag. I don't consider it a lot for the comfort we get.

Why the heck is he using a small hole saw to cut a hole. Get a zig saw.
Saw these things in Düsseldorf yesterday. Puzzled me. If you can't stand the rolling of the boat, why not buy a real boat with a mast and sails?
Be cause most people on sailboats these days don't know enuf to use the sails for steadying.
It's funny how many sailboats we talk to are changing to a trawler. I wounder why?
@@mvmoondance1283 Because they're too old to sail a proper boat
Because it might be what they want. People are allowed to have different goals and ideas. Even if you perceive them to be "wrong" according to your high standard
Moondance? You should have hired someone to suggest a real name.
When you grow up and can buy a boat of your own, you can name her what ever fits YOUR heart.
